I feel like I need to outright say this, I think it's flat out foolish to withhold tech with the intent to surprise the Reapers due to the fact that they are at least a billion years old. The only real thing that is unique to Revy that the Reapers have never seen is the Arc Reactor. Otherwise they'd likely seen everything and aren't remotely surprised by say a MK2 suit considering that Hoyr outright admitted that even with a mark 2 suit we would have had a lot of trouble unless we got the really big improvements like adding Unobtanium.
Another thing to say now, people really need to stop acting like Revy is so advanced the Reapers are shocked at her stuff, they aren't since a lot of our stuff isn't actually that unique. For gods sake the front page has numerous bonus comparisons with tech with the Reapers being presented as top tier. What makes Revy unique is that she can eventually match the Reapers tech with her own by her own brains given time and build up. As is while keeping some of our stuff secret when it makes sense like the MK3 reactors anything else is just needlessly crippling us.
Another thing is that crippling paranoia just seriously hurt not just the narrative of a story but the questers themselves. I've seen numerous times questers go way overboard with the paranoia to detrimental levels. The other problem is that it is absolutely maddening to make awesome things and then never use them due to crippling paranoia. There is even a trope for that,
too awesome to use, which is basically when you have a powerful item that could be extremely helpful but refuse to use it with it getting so bad you may end up going an entire game without using your best stuff.
Heck, just a few updates ago people were thinking that we were completely untouchable navy wise. And what happened? We got caught by total surprise and got beaten several times in naval space and even sent back because the other guys were also catching up. If people had suggested hiding our new tanks we likely would have been in serious trouble on the groundside as well. It just doesn't work, especially since we are still quite a bit behind on the Reapers on numerous areas and on top of that they are not going to be surprised since they are expecting Revy to have bullshit on her side.
I'd also really rather avoid the issue of not having any of our super tech around when we do get attacked or before things go to shit.
SA is already saving new the ships they get from Revy probably for a final push. I think it was two posts ago when it was said ships being delivered were disappearing. It shows that even SA knows the wisdom of keeping cards to their chest.
No, the SA did have Pynda's defending Sol and IIRC they played a big role in holding off invading fleets. So they are blatantly using a number of them.
Secondly do you think SA is going to buy the new armor of it's only a general increase? Why buy better quality when the enemy isn't fielding anything that takes it out. You might as well go for quantity unless MK 2 is going for the same price point.
We have real life examples of armies giving the best gear to their best men. This is why I pointed out that the Mk2's would likely be given to their elites like the N soldiers.
As for your thoughts on what the four eyes would do. Your plan doesn't make much sense since they can't develop as fast it makes more sense to develop counters to specific things. It's like when you play a game you can't anticipate everything but you study the meta for the most likely.
The more someone meets something on the field the more likely a counter will happen.
This doesn't make sense and I pointed out why. It's because research takes so much time that trying to counter a specific thing is impractical in numerous cases. In fact it's the most impractical against someone like Revy who literally constantly invents new tech in months. For gods sake to see how ridiculous someone like Revy is within 2 quarters PI invented Quantum Comms, UV rays, a giant mech that is a one man tank, UV lasers, miniaturized lasers, hacking and construction VI, swarm programming and overall improvements to existing weapons like arms and armor on par with Specter gear. There is a reason I keep saying that trying to come up with counters for specific tech belonging to Revy being extremely foolish since at the time she could have invented a hal dozen new tech.
I mean when we went up against the giant robot did we make tech specifically to counter it? No we did not, we did things like make miniaturized lasers, entirely new tank designs and overall improved existing gear for the SA.
The reality is that if the Batarian's wanted a counter to one of our techs they'd just keep working on making the best weapons possible general wise since at least with that strategy if they wanted to eventually make a gun that can hurt a MK2 it would apply to numerous other enemy units. That or just make their own power armor which I imagine they already have and are still making further improvements on.
